Thanks for the explanation. Cannot say it’s true for Elin but I have seen blond women I thought sure looked “born that way” with seemingly dark roots. You have the answer.
Is Kate Moss natural?
In some photos Elin has hair that looks plated together and stuck together which is a sign of using hair coloring. Lots of women get that stuck together effect and would look prettier if they skipped the coloring. In other words some hair takes to coloring better than others. If you can pull it off then do it. But cheap looking dye jobs .....
Also light and shadows falling on blond hair and days gone with out a wash (the oils settle on the hair to give it a darker appearance) can register a bit darker color in pictures. You can also often tell by skin color if the woman is a natural. Much of this is hard to decipher in pictures.
Elin is clearly a natural blond (although she may get highlights to enhance the lightness especially now after the children.)
My guess is that Kate Moss is a brunette.
